How to know the people on my website are from which country?

Folks, How do I know the people are from which country surfing my website? I know google analytics will give this but it gives at the end of day. So I want to know who are all accessing my site from which country. Any other tool does this instantly?

You can go for "statcounter". All you need to do is sign up and insert the code on your website. There is a tab in your account "Country/State/City/ISP", there you can see visitor come from which country. I am using this on my website: Online PNR Status.
